BLT on Duet wifi problem

Did you update your deploy and retract macros? Please post those.
Also test if M401 and M402 work to deploy and retract the pin.

And for good measure include the results of sending M122 and M98 P"config.g"

Here is the home all. Thanks for the tip on the code mode.

@gibsea402 This is the section of your homeall that you want to change

G1 H1 Z-395 F360        ; move Z down stopping at the endstop
G90                     ; absolute positioning
G92 Z0                  ; set Z position to axis minimum (you may want to adjust this)

It is using a G1 H1 homing move for Z (i.e. using an endstop which you don't have!), rather than a probing move using the BLTouch. For this you would want to use a G30 probing move (https://duet3d.dozuki.com/Wiki/G30)

So, I would suggest replacing those three lines of code with:

G90    ; set absolute positioning
G1 X150 Y150 F1800   ; move quickly to bed centre - May need to change the X/Y values to suit your printer size
G30  ; probe with BLTouch

You'll see that these commands are in @Arnold_R_Clark's homeall file (though he also has a bunch of extra stuff which may confuse things).

Hi here is the following. I think the issue is that the macro is not updated. But i am not sure how to do that.

Pin down: M280 P3 S10 I1
Pin Up: M280 P3 S90 I1 ; retract BLTouch

If i click on the macros in the web browser they do not work. But if i send the commands M401 and M402 they work.

Result of M122:

This seem to work. But if i just give the g30 command the probe is not deploying.

Which macros exactly are you clicking on? M401 and M402 call the deployprobe.g and retractprobe.g files in the /sys folder

Pin down: M280 P3 S10 I1
Pin Up: M280 P3 S90 I1 ; retract BLTouch

Those are incorrect for RRF3. Remove the I1 and instead of P3 you'd use P0 since you are using servo pin 0

M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch

M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
M950 F2 C"fan1" Q500 ; create fan 2 on pin fan1 and set its frequency
M106 P2 S1 H1 T45 ; set fan 2 value. Thermostatic control is turned on

One of those fan1 should be fan2

Thanks! this helped alot! its all working now
